FASTENING FOR BOTTLE-STOPPERS.

SPECIFICATION forming part of Letters Patent No. 388,854. dated September 4, 1888.

Application filed February 3, 1888. Serial No. 202,867. (No model.)

T all whom, it may concern.-

Be it known that we, GEORGE A. GEMUN- DEN and ALBERT F. GItR'rNER, both of Savannah, in the county of Ohatham and State of Georgia, have invented certain new and useful Improvements in Fastenings for Bottle-Stoppers, of which the following is a specification, reference being had to the accompanying drawings, and to the letters of reference marked to thereon.

The invention is intended to take the place of the present plan of wiring bottles or such vessels whose corks or stoppers must be held in place, either because of the pressure of the :5 contained fluid or for other reasons.

.In carrying out our invention we employ a bottle or vessel having a groove of required shape in its neck, into which a metal deviceis pressed for retaining the cork or stopper.

The metal device consists of one or more washers and a guard in one piece. The washers are flat and of disk form and the guard is bent over upon them, its center being bent up so as to form an arch or bow. A slightpressure on the arch will straighten out the guard and force it into the groove, so as to hold the washer or washers in place and prevent the cork or stopper from coming out. The opening in the neck of the bottle is smaller in diameter below the groove than above it, a shoulder being thus formed on which the washer can rest, and so be prevented from falling below the groove.

In the drawings, Figures 1, 2, and 3 show different forms of the metal device, consisting of two washers and the guard, before folding. Figs. 4 and 5 show a single washer and the guard before folding. Figs. 6 and 7 are seetional views showing the washers and guard folded and applied to the bottle, the guard being arched, Fig. 6 showing the double washer, and Fig. 7 a single washer. Figs. 8 and9are similar views showing the guard straightened out and forced into the groove. Figs. 10 and 11 are plan views of the washers and guard when the guard is straightened out, and Fig. 12 is aview of the metal device shown in Fig. 3 when folded.

Similar letters of reference indicate similar parts in all the figures.

A represents the washers, and B the guard, which are struck out in one piece from any suitable elastic sheet metal. The washers and guard may, if preferred, be perforated at their centers, as shown in Figs. 1 and 2, for the purpose of allowing a corkscrew to be inserted when it is required to draw the cork from the bottle.

G represents the upper portion of the neck of a bottle having near its end an interior cir- 6o cumferential groove, 0, molded or blown therein. The opening in the neck of the bottle is smaller in diameter below the groove than above it, as shown, a shoulder, 0', being thus formed, on which the washer rests.

1) represents a cork or stopper.

In operation the metal devices are folded as shown in Figs. 6 and 7, the guard being arched, and when the cork has been forced into the bottle, so that its top will be on a line with or just below the shoulder a, the metal device is inserted, and by applying pressure to the arched guard it will be straightened out and forced into the groove 0, thus holding the washers in place and preventing the cork or stopper from being ejected by the pressure of the fluid contained in the "cssel.

The metal devicesillustrated in Figs. 1, 2, 4, and 5 are best adapted for use when the fluid in the vessel has no inherent pressure when first put in the bottle, but from which a pressure may be afterward generated by steaming or otherwise. \Vhen, however, our device is to be used in connection with bottles containing soda-water, aerated mineral waters, and the like beverages, where the cork has to be held in the bottle by means of the plunger, which forces it into the bottle until it is secured, we prefer to use the device illustrated in Figs. 3 and 12, which is provided with a slot, b, in the guard and one of the washers, and with a recess, b, in the other washer, to enable it to clear the plunger while being forced into the groove in the bottle. The slot and recess also allow a corkscrew to be worked into the cork.

Having described our invention, we claim- 1.. The combination, with a bottle having near its month an interior projecting shoulder and a circumferential groove, of a cork fitting the neck of the bottle below the groove, and a securing device adapted to rest on the projectvided with the slot 7) and recess I), snhstan- 10 ing shoulder and consisting of a metal washer tinlly as specified. and guard in one piece, the guard being arched In testimony whereof we have hereunto set and bent over on the washerandadapted, when our hands and seals. straightened out, to he fOlt'iOdlllljO the groove, I G.
